Neck Spasm, then sight went white/yellow

Male, 33, southeast USA. Today while sitting on the couch and moving my head i feller a strong cramp in my neck. I moved my head around to get it to stop. As soon as the camp resolved, a large white spot obscured about 80%of my vision, then my vision went back to normal but blurry and slightly yellow for a couple of minutes. Did I just turn my head the wrong way? Was that a miniature stroke?
